The Land Rover 23 J is a 1,999 cc, inline — four turbo — diesel engine produced between 2020 and 2023. Part of Jaguar Land Rover's Ingenium engine family, it features high — pressure common — rail fuel injection, a variable geometry turbocharger (VGT), and dual overhead camshafts. In standard tune it delivers 110 kW (150 PS) and 360 Nm of torque, with higher — output versions producing up to 132 kW (180 PS), offering a balance of efficiency and responsive low — end performance.

All production years (2020–2023) comply with Euro 6d-Final emissions standards .
The Land Rover 23 J is a 1,999 cc inline-four turbo-diesel engine developed for compact and mid-size SUVs (2020–2023). It integrates variable geometry turbocharging with Bosch CRS 3-20 common-rail injection to deliver strong low-end torque and improved throttle response. Designed to meet Euro 6d-Final regulations, it balances real-world drivability with stringent emissions control through DPF and SCR systems.

The Land Rover 23 J was used across Land Rover's Evoque/Discovery Sport platforms with transverse mounting and adapted for the Defender's longitudinal architecture. This engine received platform-specific tuning-shorter intake manifolds in the Evoque and revised torque mounts in the Discovery Sport-and from 2022 the Defender 90/110 adopted the SCR-enhanced 23 J variant with updated ECU mapping, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The 23 J offers strong low-end torque and good fuel economy, but pre-2022 models have known DPF clogging issues in urban environments. Later revisions (2022+) show improved reliability with updated ECU calibration for regeneration. When maintained properly—using correct oil (5W-30 JLR STJLR.51.5004) and adhering to service intervals—these engines can reliably exceed 150,000 km.
Primary issues include DPF clogging from short trips, AdBlue/SCR system faults, VGT actuator sticking, and high-pressure injector wear. These are documented in Land Rover service bulletins P313-0021 and P312-0056. Regular highway driving and using quality diesel significantly reduce failure risk.
The 23 J is used in the Range Rover Evoque (L551), Discovery Sport (L550), Defender 90/110 (L663), and E-Pace. All models from 2020–2023 with the D150, D180, or D200 diesel designation use this engine. All units comply with Euro 6d-Final emissions standards and require AdBlue refills.
Aftermarket ECU tuning is common on the 23J platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
In real-world conditions, expect 7.0–8.0 L/100km (36–40 mpg UK) in urban driving and 5.8–6.5 L/100km (43–48 mpg UK) on highways. Combined consumption is approximately 6.5 L/100km (43 mpg UK). DPF regeneration cycles may temporarily reduce efficiency.
Yes. The 23 J is an interference engine. If the timing chain fails or jumps, piston-to-valve contact can cause catastrophic internal damage. Chain maintenance and timely oil changes are essential to prevent tensioner failure and ensure long-term reliability.
Land Rover specifies 5W-30 synthetic oil meeting STJLR.51.5004 standard. This low-ash formulation protects the DPF and SCR system and ensures proper lubrication of the twin-chain timing system. Oil must be changed every 15,000 km or annually to maintain engine health.
